Change Request | Description
--- | ---
10051, 10130 | FIXED: Large UIM messages, such as UM responses, can become corrupted when transferred between Topic Resolution Domains by a DRO.
10085, 10086 | FIXED: For UM version 6.10 (only) running on "big-endian" machines (e.g. SPARC), 64-bit values in UM packet headers were not properly swapped, with the result that for certain features, big-endian machines cannot interoperate with little-endian machines. The problem is most visible with the ULB feature, and the DRO.
10050, 10054 | FIXED: For UM version 6.10 (only), the DRO is not able to run on the UMS or UMP products' "lbm" libraries.
